ClamAV < 0.94.2 cli_check_jpeg_exploit() Malformed JPEG File DoS

medium Nessus Plugin ID 35009
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote antivirus service is vulnerable to a denial of service attack.

Description

According to its version, the clamd antivirus daemon on the remote host is earlier than 0.94.2. There is a recursive stack overflow involving the JPEG parsing code in such versions. A remote attacker may be able to leverage this issue to cause the application to recursively scan a specially crafted JPEG, which will eventually cause it to crash.

Solution

Upgrade to ClamAV 0.94.2 or later.
